Sonar Altimeter Data Help In Fly Ash Pond Dewatering Project

Fly ash ponds can be dangerous to surrounding soils and waterways if they’re not constructed correctly . But even if they’re built with linings of clay soils or membranes, there is still need to manage their functions to ensure that what they hold -- byproducts of coal burning -- stays put. Experts at Los Alamos Technical Associates (LATA) have some experience with that. They recently helped manage the water levels in a fly ash pond near a coal-burning power plant in Kentucky. The project involved using a Tritech Micron EchoSounder DST Precision Sonar Altimeter to keep water levels in the fly ash pond high enough to ensure that pumps sending water out to nearby streams didn’t transport any sludge. “We were doing a dewatering job,” said Tim Hoehnke, project manager at LATA.

Vegetation Type Has Role In Future Sierra Nevada Stream Flows

Precipitation is important for stream flows in the Sierra Nevada mountains, but new findings from scientists at the University of California, Santa Barbara, indicate that surrounding vegetation changes due to climate warming may have just as great an effect. In some cases, the impacts of vegetation changes were found to have greater effects on stream flows. Scientists at the university used a regional hydrological model in the effort to consider the possible future distributions of vegetation in the Sierra Nevada. The two main types of vegetation they looked at were shrubs and trees. Though there is a conception that trees are always going to use more water than shrubs, the investigators found that notion didn’t always hold up.

Glacier National Park: Sperry Basin Lakes Hold Food Web Mysteries

Most folks don’t question why a lake sits where it is. But at some point in our planet’s history, it’s safe to assume that the water body didn’t exist. Something had to have happened to bring about its creation and stable status as a freshwater ecosystem. Observing such a transition is incredibly difficult, as we don’t live long enough to view planetary timescales as they shift and mold our world to create new terrains and ecosystems. But things are getting easier nowadays, thanks to new technologies and a globally connected world that allows the scientists of today to access more of the Earth’s wonders. Clearly one of those is Glacier National Park, a beautiful place to study with lakes that just may hold answers to questions related to the birth of our freshwater treasures.
